- You don't say where you live, so I don't know if $600/yr is a lot...
- PSU, is that Penn. State? Living in sunny California, I can't help there...

- Yes, it will. To a first approximation your rate of heat loss is directly
- proportional to delta T, and your gas usage directly proportional to your
- heat loss. The lower your thermostat setting, the less you will pay. Keep
- the setting at the lowest level that is reasonably comfortable. Get a
- night setback thermostat, so you can turn it lower when you're asleep but
- have it warm when you get out of bed (even in sunny CA, mine paid for itself
- in a couple of months).
-
- The *only* case I'm aware of where the above rules of proportionality don't
- apply is when you have two different heating means, with different costs.
- This commonly occurs with heat pumps, where a backup system (often electric)
- kicks in if the thermostat setting is "x" degrees higher than the current
- temperature. In this case turning up the heat by a large amount (either
- manually or automatically) can trigger the (expensive) backup system. There
- are setback thermostats designed to deal with this, however.
